well, since there is absolutely NO read given on villian I think his range here is enormous. Is he LAG enough to represent an ace when you make a weak bet at him (which you did on the turn).

Maybe he actually has an ace and thinks his hand is good. Only hands to be afraid of are AK and JT or a slowplayed 55. JT is the only real thing I'd worry about here. I would push this turn 100% and hope to fill up on river if I'm up against JT. Otherwise you are good.
